Chapter 4: Starting and Setting Up the Instrument
The QPix 420 Colony Picking System must be located in a well-ventilated area. The instrument
is installed by approved personnel with the software pre-installed on the system computer. For
more information about the installation requirements, see

Start-Up and Shutdown Procedures
Before using the instrument, confirm all the tasks listed in Pre-Power-Up Check List.
Pre-Power-Up Check List
Confirm that the Emergency Stop button on the front of the instrument is pulled out. The
instrument cannot start if the button is pushed in.
Confirm that the instrument bed is clear of obstructions and loose items.
Confirm that all motor tracks are free of obstructions.
Confirm that there are no obstructions to the movement of the head.
Confirm that the acrylic door is properly closed.
Confirm that the power cord for the instrument is properly connected and that power to the
power outlet is functioning properly.
Confirm that the air pressure delivered to the filter regulator inlet is from 0.69 MPa to
0.83 MPa (100 psi to 120 psi).
If you are using a standalone air compressor, confirm that the power cord for the
compressor is properly connected and that power to the power outlet is functioning
properly.
Powering On the System
To power on the system:
1. Confirm all the tasks listed in Pre-Power-Up Check List.
2. Power on the air source.
If you are using a laboratory built-in air system, verify that the supplied air pressure is
from 0.69 MPa to 0.83 MPa (100 psi to 120 psi) and then switch on the control valve.
If you are using a standalone air compressor, switch on the compressor and then verify
that the supplied air pressure is from 0.69 MPa to 0.83 MPa (100 psi to 120 psi).
3. Push the Start button on the front panel.
The Power On icon displays on the front panel. If the power to the system does not turn on,
it is likely that the door is open or the Emergency Stop button is pushed in.
The instrument cycles through the various startup processes indicated on the front panel.
4. Check that the Air icon on the front panel displays indicating that the air pressure from the
air source is sufficient for operating the instrument.
5. Switch on the computer and wait for it to initialize the operating system and to discover the
local network that connects the instrument to the computer.
Note: If you start the software before the network has been discovered, a message
displays notifying you that it cannot find the instrument.
